When this powerful divination is cast, the caster chooses the target area and a time in the future. This spell creates an illusion of the target area cantered around the caster. To be precise it creates an infinite number of illusions of all the possible ways the area may appear. As these images layer, the most probable possibilities appear strongest, and the least probable seam fainter. In order to glean useful information from this vision the caster must succeed in a scry check. This scry check may be attempted while maintain the spell. The DC varies according to how precise information the caster is looking for, and far in the future she looks. One scry check may be made per round, and different information may be sought each check. Since the remote scrying sensor only exists for one exact instant in all realities, it cannot be seen. Anyone in an area at the exact instant it is targeted by a Probability Scry is entitled to a scry or intelligence check (DC = caster's scry check + 5) to feel the presence of the sensor. Remember the only information that can be learned is relative probability. The focus of this spell is 10,000 gp worth of very finely cut diamond crystals that are thrown in the air as this spell is in effect and must be collected from the ground when the spell expires. (Focus) One of these "diamond chips" invariably finds itself in the target area at the target time (Material Component)
Information:
DC 25 - Basic - How will the walls most likely look, will a castle probably still be there, or Yes/No could a particular person be there.
DC 30 - Intermediate - Who will most likely be in the area? What will they most likely be doing?
DC 35 - Advanced - Any information pertaining to the elapsed time between now and the sensor. How probable is it that a large dragon passed through the area. When was the most probable time of his passing?

Miscellaneous:
The DM is well within his rights to modify the DC scry check in accordance to how much activity an area has. Sealed tombs are easy to glean information from, while many mages find it impossible to target large cities.
